Air bubbles affecting pH?


New Member
Heres an example for ya...Last night, I mixed my organic nutes into a pail of water and balanced my pH to 6.5. I figured I'd throw my air stone into the mix and let things work overnight. This morning I rechecked pH and got a higher reading of 7.4. What happening here?:hmmmm: Should I balance the pH back down or is the pH before adding the air correct?
